SCOPE The material defined by this specification is a molded-in-color low gloss, polypropylene copolymer that is UV stabilized for unpainted int

3、erior applications with good impact and thermal performance. 2. APPLICATION This specification was released originally for material used for interior trim components. 2.1 LIMITATIONS This material is not intended for painted applications. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATE

4、RIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). Note: Many 4D resin specifications prior to 2011, identified certain requirements with the symbol (s), which indicated that the mean and +/- 3 sigma values were t

5、o be reported. The specification minimum, maximum or range was established using 3 sigma data. For 2011 and beyond, refer to Table 1 for number of samples required for each test. 3.1.1 This specification is based on virgin materials, however materials with recycled content as defined by WSS-M99P42-A

6、 (post-consumer and/or post industrial recyclates and repolymerised recycled materials) should be used whenever technically feasible. The use of regrind is permitted, for economic / environmental reasons, Follow CAD and Drafting Standard E-4 for requirements and identification of regrind content. 3.

7、1.2 Materials used in interior applications must meet the requirements outlined in WSS-M99P2222-D1/Latest, Performance, Vehicle Interior Environment Quality Material/Component Requirements. Data must be included in material submission package. 3.1.3 Performance Criteria: Parts using this specificati

8、on shall meet the appropriate performance specification, WSS-M15P4-F/Latest for Hard, Interior, Molded-in-Color component performance. ENGINEERING MATERIAL SPECIFICATION WSS-M4D638-B Copyright 2015, Ford Global Technologies, LLC Page 2 of 8 3.2 SAMPLE PREPARATION Unless otherwise specified all tests

9、 shall be carried out on injection molded, one-end gated test specimens. The test specimens A and D shall be molded using molding conditions defined in ISO 1873-2. No annealing is allowed. See Table 1 for the number of specimens required. Specimens shall be as follows: Specimen A 150 minimum x 10 x

10、4.0 +/- 0.2 mm (ISO 527-2, Specimen Type 1A) Specimen B 355 x 100 x 1.0 +/- 0.1 mm (ISO 3795) Specimen C 145 x 60 x 3.2 +/- 0.2 mm Specimen D Center of Specimen A. 80 x 10 x 4.0 +/- 0.2 mm Specimen E 100 mm diameter x 3.2 mm Specimen F 80 mm diameter x 3.2 mm Specimen G 90 mm x 200 mm Specimen H 50

12、ter and allow them to cool for one hour. Conduct a tactile evaluation and report any tackiness. Visually evaluate and report any spewing or other exudation. After exposure the material shall show no fading or color change in excess of specified AATCC rating. In addition, there shall be no cracking,

13、crazing or other deterioration. Use regional choice colors for initial approval and report color house used. For color durability submissions, test all program colors. 3.3.2 Resistance to Scratch and Mar (FLTM BO 162-01, Specimen I) Scratch Rating 2 at 2 N, max Whitening/Color Change Rating 1 at 7 N
